Dual-link DVI vs. Single-link DVI

In addition to the fact that DVI can be adapted to transmit a purely digital DVI-D signal or a combination of analog and digital DVI-I, there are two different versions that differ in data throughput. The original version is called single-link, and you can get by with it on all Full HD monitors at the standard 60Hz refresh rate. The dual-link version doubles the bandwidth and can be used for resolutions such as 2,560 × 1,440 at 60 Hz.

Electrical Power Input

Electrical power input is the amount of power that flows from the socket or power supply. The output is always lower than the input. This is where the concept of perpetual motion comes into play, because there will always be some energy loss (thermal, motion or sound). This creates the difference between input power and output power.

Types of Laptop Adapter Connectors

Laptop adapters are used to power and charging a laptop's battery. In addition to the adapter provided by the manufacturer, it is possible to use other models. It is crucial to select an adapter with the correct connectors. What are the basic types?

Screen Size

Screen size is measured in inches (1"=2.54cm) and it is measured diagonally from the bottom left corner to the top right. Models with larger dimensions provide more working and viewing space, whereas smaller laptops are more suitable for work on the go.

4K Resolution (Ultra HD)

4K technology offers four times the detail when compared to FullHD, so when you look at your favourite movie on a 4K TV, you'll find details you've never seen before.

VESA Mounting

VESA uchycení je normou, která usnadňuje orientaci zákazníka při nákupu držáku k televizi nebo monitoru. Sjednocuje vzdálenost upevňovacích otvorů, tedy rozteč, na zadní straně televize a držáků. Jak to funguje a jak se v číslech orientovat, zjistíte v našem článku.
